Mech_Engineer said:I think it means for a 30 psi head (back-pressure) and nominal flow rate the pump will pull 2.2 amps. If you're only seeing 1.4 amp draw it's likely because you have a back-pressure lower than 30 psi on the pump when its running.
A 12V 30 psi pump is a type of pump that operates with a 12-volt power source and is capable of producing a pressure of 30 pounds per square inch.
A 12V 30 psi pump is commonly used in applications such as water circulation, irrigation, and fuel transfer in small engines or vehicles.
Some benefits of using a 12V 30 psi pump include its compact size, portability, and ability to be powered by a 12-volt battery, making it suitable for use in remote locations or areas without access to electricity.
When choosing a 12V 30 psi pump, factors such as flow rate, pressure requirements, power source, and construction materials should be considered to ensure the pump meets the specific needs of the application.
Regular maintenance for a 12V 30 psi pump includes cleaning, inspection of seals and connections, and checking for any wear or damage. It is also important to follow the manufacturer's instructions for proper storage and use.
